My newspaper advisor (who is also an English and journalism teacher) is a self-confirmed ENTJ. Now, I'm not an INTP, but I used to think I was and my Ti usage score is just a point or two below my Fi score. Needless to say, I bear some similarities to an INTP.
Personally, I find her excruciatingly ruthless when it comes to fairness for all and her work ethic is scary. She doesn't seem to have an excellent grasp of feelings either. I have not had that many substantial conversations with her, if any at all, but I find we get along pretty well. I know ENTJs are considered the INTP's "natural partner," and I think the pairing is cute. However, if you ask me, INTJ + INTP = MUCH cuter.
Something that bugs me about her, I should note, is although she is annoyed to no end by idiocy and ignorance, she seems to put up with plenty of ignorant people just for the sake of conversation. She will talk to the dumbest people just in order to have a conversation; her extroversion is pretty dominant. Also, the whole "hates to be bored" characteristic is also very dominant.
